Increasing material’s strength has been a significant matter since the beginning of engineering to up to now. It has always been paid attention by engineers. A variety of methods has been presented for increasing strength, stability, working range and material working life by development of engineering sciences and more identification on material properties and the material behavior, which are ...

This paper investigates the microstructural evolution and grain refinement kinetics of a solution-treated Cu-0.1Cr-0.06Zr alloy during equal channel angular pressing (ECAP) at a temperature of 673 K via route BC. The microstructural change during plastic deformation was accompanied by the formation of the microband and an increase in the misorientations of strain-induced subboundaries. We argue...

An empirical method of non-destructive testing of a material was developed using pulse transmission by acoustic emission transducers to determine plastic deformation of 304 stainless steel specimens. This was done by means of comparison of pulse signals detected in an undeformed section with the pulse signals detected after passing through the deformation zone in the specimens. The pulse signal...

Contact between a slider and bit patterned media (BPM) is investigated using finite element analysis. The effect of contact conditions and material properties at the interface between slider and disk on plastic deformation and temperature is studied. In addition, the planarization of bit pattern media on temperature and plastic deformation is investigated for different filler materials. It is f...

Plastic deformation behavior of Cu/Ni/W metallic multilayers with individual layer thickness ranging from 5 nm to 300 nm is investigated by nanoindentation testing. The experimental results reveal that the composite still exhibits indentation-induced plastic deformation instability and the loss of strain hardening ability at the nanometer scale even if the composite contains two kinds of layer ...
